According to research that just released in the journal Earth’s Future, rocket launches are having the greatest negative impact on the climate. Researchers from UCL, the University of Cambridge, and the Massachusetts Institute of Technology were in charge of the investigation (MIT). The team found that in 2019 launchings and re-entry will have the following effects: “impact of projected space tourism scenarios is based on the recent billionaire space race.”
According to the study, there is now little ozone loss as a result of rockets. However, the consequence is forecasting to be substantial in the coming years “due to the pollutants from solid-fuel rockets”. According to researchers, the growing pattern indicates that there is a possibility of ozone layer thinning in the Arctic in the springtime in the coming years. The team attributes this to an increase in commercial space travel.
On the period of study, the team figured out that the “black carbon (soot) particles emitted by rockets are almost 500 times more efficient at holding heat in the atmosphere than all other sources of soot combined (surface and aircraft) – resulting in an enhanced climate effect.”
The group collected data on the rocket launches that happened in 2019. The substances employed in each of the 103 launches were examined, and information regarding reusable rockets and space debris re-entry was also properly considered. Also included were the most recent demonstrations by space tourism businesspeople like Virgin Galactic, Blue Origin, and SpaceX.
